Chapter 4 Module Configuration, Output, and Input Data

Output Overcurrent (Out0Overcurrent to Out3OverCurrent)

The output overcurrent bits are set (1) when the module is in an overcurrent

condition. These bits also show whether the output is latched off, because the

output remains in the off state and these bits remain on until the ResetBlownFuse

bit is used.

Module Configured (ModConfig)

Word 2, bit 5 is set by the module after it has accepted all of the configuration

data. When set (1), this bit confirms that the module received and accepted valid

configuration data. When reset (0), this bit indicates that the module still is

checking for errors or contains errors and the old configuration is still being used.

Invalid Output (InvalidOutput)

• 1 = an unused bit in the output array is set

• 0 = no unused bits in the output array are set

When this error occurs, the entire output array is rejected until an output array

that does not have this error is sent.

Error (GenError)

When this bit is set (1), it indicates one or more of the following errors for the

input array:

• OutnOvercurrent

• InvalidRangeLimitn

• InvalidCtrAssignToRangen

• InvalidOutput

• Ctr[n].Overflow

• Ctr[n].Underflow

• Ctr[n].InvalidDirectWrite

• Ctr[n].InvalidCounter

• Ctr[n].PresetWarning

where n indicates the counter number.

To determine which error has set the GenError bit, identify which bit is set. This

could be done by using a subroutine to examine these bits in the input array.

TIP

The module takes up to two seconds to validate configuration data.

TIP

Ctr[n].RateValid does not set the GenError bit.
